eBay Analytics ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with eBay Analytics.



LINQ provides general-purpose query facilities in .NET Framework 3.0 and above and provides one easy way to programmatically access data through from CData ADO.NET Data Providers. This example uses LINQ to access information from the eBay Analytics Data Provider.

This article demonstrates how to use LINQ to access eBay Analytics tables through the CData ADO.NET Data Provider for eBay Analytics. To do this you will LINQ to Entity Framework, which is used to generate the connection and can be used with any CData ADO.NET Data Providers to access data via LINQ.

See the help documentation for a guide to setting up an EF 6 project to use the provider.

  1. In a new project in Visual Studio, right-click on the project and choose to add a new item. Add an ADO.NET Entity Data Model.
  2. Choose EF Designer from Database and click Next.
  3. Add a new Data Connection, and change your data source type to "CData eBay Analytics Data Source".
  4. Enter your data source connection information.

    You can authenticate to eBay Analytics only via the OAuth 2 authentication method. The eBay Analytics API requires an access token created with the authorization code grant flow to authorize the requests.

    You can follow the guide in the Help documentation for a step by step guide on how to authenticate using the OAuth 2 protocol.

    Below is a typical connection string:

    OAuthClientId=MyAppID;OAuthClientSecret=MyCertID;RuName=MyRuName;InitiateOAuth=GETANDREFRESH
  5. If saving your entity connection to App.Config, set an entity name. In this example we are setting EbayAnalyticsEntities as our entity connection in App.Config.
  6. Enter a model name and select any tables or views you would like to include in the model.

Using the entity you created, you can now perform select commands. For example:

EbayAnalyticsEntities context = new EbayAnalyticsEntities(); var trafficreportbylistingQuery = from trafficreportbylisting in context.TrafficReportByListing select trafficreportbylisting; foreach (var result in trafficreportbylistingQuery) { Console.WriteLine("{0} {1} ", result.Id, result.ListingName); }

See "LINQ and Entity Framework" chapter in the help documentation for example queries of the supported LINQ.
